BACKGROUND: Administrative data has shown a lower mortality in hospitalized patients with pulmonary embolism and cancer who receive a vena cava filter. In the absence of a randomized controlled trial of vena cava filters in such patients, further investigation is necessary. Therefore, we performed this investigation using administrative data from a different database than used previously, and we investigate patients hospitalized in more recent years. METHODS: We analyzed administrative data from the Premier Healthcare Database, 2010-2014, in patients hospitalized with pulmonary embolism and solid malignant tumors...

INTRODUCTION: Vertebral hemangiomas (VH) represent the most common primary bone tumor of the spine and are rarely symptomatic. Currently, there is no consensus for treatment and many therapeutic options are available, alone or in combination including cementoplasty, sclerotherapy, surgery, embolization and/or radiotherapy. OBJECTIVE: To evaluate the clinical and radiological outcome of a multimodal management for symptomatic VH. METHODS: A consecutive prospective and retrospective multicenter study was conducted to review cases of symptomatic VHs between 2005 and 2015...

We report a case of renal cell carcinoma (RCC) metastasis to the calvarium and describe a strategy for percutaneous embolization of hypervascular calvarial tumors with intracranial extension. An elderly patient with history of RCC presented with left-sided weakness. Imaging studies showed a large right frontoparietal calvarial mass with intra- and extracranial extension. The tumor was devascularized by direct puncture tumor embolization using Onyx 18, allowing subsequent operative resection without significant blood loss or the need for flap reconstruction of the scalp...

Interventional embolization is a popular minimally invasive vascular therapeutic technique and has been widely applied for hepatocellular carcinoma (HCC) therapy. However, harmful effects caused by transcatheter arterial chemoembolization (TACE) and radioembolization, such as the toxicity of chemotherapy or excessive radiation damage, are serious disadvantages and significantly reduce the therapeutic efficacy. Here, a synergistic therapeutic strategy combined transcatheter arterial embolization and magnetic ablation (TAEMA) by using PLGA-magnetic microspheres (MMs) has been successfully applied to orthotopic VX2 liver tumors of rabbits...

Background: Primary extramedullary tumors involving multiple compartments around the spine are a technically demanding group of tumors whose extent traverses beyond the normal confines of those anatomical regions which fall in the common domain of neurosurgeons. In the following series, we present 12 patients who were diagnosed with primary spinal extramedullary tumors with multicompartmental extension, and whose surgical management was facilitated by a combined multidisciplinary approach involving surgeons of other superspecialties...

PURPOSE: In order to limit ischemia and operative bleeding during and after partial nephrectomy we developed a clampless laparoscopic technique, in a hybrid operating room, immediately after super-selective arterial embolization of the renal tumor. We evaluated feasibility and morbidity of this new approach of zero ischemia in partial nephrectomy. METHODS: We included prospectively 50 consecutive patients treated in a hybrid operating room by this new technique for a localized renal tumor in a university hospital between May 2015 and January 2017...

Percutaneous and endovascular techniques take an important role in the therapeutic management of patients with hepatocarcinoma. Different techniques of percutaneous ablation, especially indicated in tumors up to 2cm diameter offer, at least, similar results to surgical resection. Taking advantage of double hepatic vascularization and exclusive tumor nutrition by the artery, several endovascular techniques of treating the tumor have been developed. Intra-arterial administration of embolizing particles, alone or charged with drug (chemoembolization), will produce ischemia and consequent necrosis with excellent results in selected patients...

BACKGROUND: The definition of parenchymal sparing surgery (PSS) for colorectal liver metastases (CRLM) diverges requiring a clarification of the concept. METHOD: A consecutive series of patients were treated by PSS for their CRLMs, either by resection or intra-operative ablation (IOA), whenever possible a one-stage surgery and minimal usage of portal vein embolization. Post-operative complications were the primary endpoint with a special focus on post-operative liver failure...

This study describes the use of fluorescence imaging and mass spectrometry imaging, for imaging the anti-angiogenic drug sunitinib, used to treat liver cancer. These techniques allowed for the assessment of local delivery of the unlabeled therapeutic drug. More specifically, the spatial distribution of the drug and its metabolites after local administration was investigated, and drug levels in tumor and liver tissue over time were quantified. For this purpose, sunitinib-eluting microspheres were locoregionally injected into the tumor feeding arteries of rabbits bearing liver tumors...

Transcatheter arterial chemoembolization (TACE) is used as a palliative treatment for unresectable hepatocellular carcinoma (HCC) worldwide. Recently, a novel drug delivery-embolic agent, the drug-eluting bead (DEB), was introduced for TACE. There are a few reports of tumor hemorrhage after TACE using DEB (DEB-TACE) for HCC. However, there have not been any reports of hemobilia immediately after DEB-TACE for an HCC with intrahepatic bile duct invasion. Here, the first such case is reported. A 71-year-old woman was admitted to our hospital to undergo DEB-TACE for multiple HCCs with worsening left intrahepatic bile duct dilatation...

Renal angiomyolipoma (RAML), though a rare benign tumor, may impose a significant morbidity or even mortality due to its unique characteristics and the complications subsequent to its treatment. The classic tumor variant is composed of smooth muscular, vascular, and fatty components. The most straightforward diagnosis is when the fat component is abundant and gives a characteristic appearance on different imaging studies. In fat-poor lesions, however, the diagnosis is difficult and presumed a renal cell carcinoma...

Most patients with hepatocellular carcinoma present with intermediate to advanced disease, where curative therapies are no longer an option. These patients with intermediate to advanced disease represent a heterogeneous population with regard to tumor burden, liver function, and performance status. While the Barcelona Clinic Liver Cancer (BCLC) staging system offers guidelines for the management of these patients, strict adherence to these guidelines may limit treatment options for these patients. Several locoregional therapies exist for these patients, including conventional transarterial chemoembolization (cTACE), transarterial embolization (TAE), drug-eluting embolization (DEE), and radioembolization...

With the recent increase in the detection of small-sized lung nodules because of the widespread use of computed tomography (CT), limited resection and minimally invasive surgery are preferred by patients with these lesions. In particular, the detection of nodules that show ground-glass opacity during high-resolution CT has increased. Although lobectomy and lymph node dissection were the standard procedures used for treating lung cancer, limited wedge resection and segmentectomy have become acceptable for treating small-sized lung cancers with nodules showing ground-glass opacity...

Cerebellar hemangioblastomas are rare tumors of the neuraxis. Only seven cases of hemangioblastoma associated with a cerebral aneurysm have been reported. We report a case of a patient who presented with acute onset headache as a result of subarachnoid hemorrhage (SAH) and hydrocephalus. Radiographic workup revealed a hemangioblastoma with an intratumoral aneurysm. Preoperative cerebral angiography was performed for both embolization as well as characterization of the aneurysm. The patient underwent a suboccipital craniotomy for tumor resection...
